How To Coordinate The Movement Of The Stitching Machine

　　 Flat seaming machine Accurate cloth feeding can reduce the probability of jumping. The main aspects of the daily influence of cloth feeding are closely related to the height of the feeding tooth, presser foot pressure, differential delivery, needle spacing density and speed of use. The main theory of this article is that the stability of the back triangular line loop depends on the stability of cloth feeding and the proper coordination of the thread take-up cam. If the cloth delivery is not stable, the triangulation ring will be deformed or suddenly and lightly, so that the needle can not enter the triangle ring.

adjustment feed dog The principle of height should be that when the cloth feeding is completed, the cloth teeth must be returned from the bottom of the needle plate, so that the action of sewing material retrogression is not allowed. The foot pressure should ensure that the material is not slippery on the operator side. When the elastic material is large or the operator has too much power to cut the material, the differential delivery should be increased. It will be found that when the bending needle begins to enter the long needle ring, the wire loop is distorted. If the bending needle is moved a bit earlier, the bending needle will enter the coil, and then the friction between the bending needle and the wire will cause the deformation of the coil. When the bending pin enters the coil completely, the coil will not be able to slip out of the curved needle tip.

The crooked hook is not on the line. According to the distortion of the needle and thread, the needle can be tilted to a certain point, and the wire ring formed is unstable because the long needle is the farthest needle of the crooked needle hook. When the quality of the wire is not good, the coil will distort and distort when the coil is forming a certain range, so that the needle is not easy to hook into the long needle coil. So the coil formed is also the biggest one. It is the needle coil that caters for. Curved needle Enter the line loop (the needle can only change direction slightly, if too many will cause jump needle). The needle spacing is also small, so the density should be appropriate, and it should be small in the possible range. Because when the bending needle enters the long coil, the bending needle is just in contact with the line of the pinhole. The needle moves to the left, and the contact between the bending needle and the machine needle line, the two friction each other, driving the coil to the left deformation, causing the coil to distort and change faster. Too fast will make the sewing material float or not be pressed by the presser foot instantly.
